To all whom it may concern:

Be it known that I, ALBERT BYINGTON, a citizen of the United States, residing at B0- chelle, in the county of Ogle and State of Illinois, have invented certain new and useful Improvements in Automatic Oilers, of which the following-is a specification. V

The object of this invention is to construct an automatic oil-feed for steam-engines.

In the accompanying drawings, Figure 1 is a plan view, of the oil-feed in which the parts are in working position. Fig. 2 is a similar view in which the parts are out of gear. Fig. 3 is a face elevation. Fig. 4 is a side elevation. Fig. 5 is a face view of the worm, showing its connection with the pin. Fig. 6 is a plan view showing the Worm disengaged from the pin. Fig. 7 is a transverse section showing the connection between the piston and frame.

A cylinder 1 has a stufiing-box 2 at its upper end and its bottom provided with feet 3, by which it is secured to a support. A piston 24 is located in the cylinder and is moved vertically by a rotating screw 5, having a screwthread connection therewith. From the cylinder rises an arm 6, having a rib 7. From the upper end of the piston extend lugs 8, which engage the rib 7 and hold it against rotation, but permitting it to move vertically thereon. An oil-supply tank 9 has a connection with the cylinder by the pipe lO, and a valve 11 regulates the flow of oil to the cylinder. A pipe 12 connects the cylinder with the engine. The upper end of the arm 6 supports a plate 13, to the upper face of which is pivoted a box 14:, supporting one end of a shaft 15. The other end of this shaft is supported in a box 16, having a movable connection with the base by the bolt 17 moving in the slot 18, and a wheel19 serves to clamp the box to the plate. To this shaft is secured a sawtoothed wheel 20, and a worm 21 is loosely supported thereon. A coiled spring 22 is placed on the shaft between the saw-toothed wheel and the worm 21. An adjustable collar 23 surrounds the shaft between the spring and saw-toothed wheel and is adjustable in the lengthwise direction of the shaft by means of the screws 24, by means of which the tensionof the spring is adjusted. A pin 25 is passed through the shaft 15, and the end of the worm next this pin has a series of recesses 26 to receive the pin, thereby forming a clutch connection between the shaft and worm.

' A worm-wheel 27 is secured to the upper end of the screw 5, and the under face ofthis Worm-wheel has a collar 28, which is held against lengthwise movement by the bearing 29, but is permitted a rotary movement. To the upper end of the screw-shaft is secured a hand-lever 30. A bar 31 is pivotally supported by the shaft between the saw-toothed wheel and box 14:, to which is pivoted a dog 32, adapted to engage the teeth of the sawtoothed wheel, and a spring 33 holds it in engagement with the teeth. The lower end of this bar is provided with'a series of holes 3 1 and supports a yoke 35, to which is connected a bar 36, and to the free end of this bar is pivot'ed ayoke 37. This yoke supports a rod 38 in a manner to permit an adj ustinent of the rod in its lengthwise direction. This rod has a connection with the'valve-rod of the engine, by means of which the bar is oscillated and an intermittent rotary movement imparted to the saw-toothed wheel through the dog connection.

A flat spring 39 issecured to the bar 16 and rests upon the worm 21, which prevents backward movement of the worm. With the'piston down to its fullest extent the worm 21 is disengaged from itsjconnection with the wheel 72 by loosening the hand wheel19 and swing ing the box 16 and shaft 15, the pivot of the box 14.- acting as the center of motion. By the hand-lever 30 the screw 5 is rotated to the left hand, which will raise the piston and draw oil from the tank 9 into the cylinder 1, the valve being previously opened, and when the cylinder is full the valve is closed and the worm moved into engagement with the wheel, and an intermittent rotary movement will be imparted to the screw 5 to the right hand, which will move the piston down and force the oil through the pipe to the engine. Should the piston strike the bottom of the cylinder or in any manner be prevented from descending, thereby holding the wheel 27 stationary while the shaft 15 is rotating, the effect will be to move the worm bodily toward the sawtoothed wheel 20 against the action of the spring by the worm running back on the wheel 27. This movement of the worm will disenamass gage it from the pin 25, thereby breaking the connection between the worm and shaft 15 and preventing breakage of the parts.

I claim as lily-invention 1. In an automatic oiler, a cylinder, at pis ton therefor held against rotation, a rotating worm-wheel having-a screw connection with the piston, a shaft, a worm mounted on the shaft, a clutch connection between the worm and the shaft actuated by resistance to the downward movement of the piston.
